Hey mate, I have to agree... I just to have this wing on my R33 just for something different (just the wing itself without sidescraps) - but I gotta say, it looks nice but the only thing I didn't like was that it lent towards the back too much - if it was straight up and across like a T then that's fine, but it kinda "ducktailed" to the back too much which made it look rather funny.
Oh well, everyone to there own.
For a R34 - I recommend a OEM Wing.
go here: www.carmate.com - browse for your model, go to Wings and then look for the above wing I described - bet you will like it.
I was going to put this wing on my R33 with custom bootlid but ended up going GTR wing as with R33's only the GTR wing does it.
Good luck.
